SMOKING-PIPE.

Specification of Letters Patent.

Patented Oct. 12, 191.5.

Application filed September 3, 1914. Serial No. 860,051.

the art to which it appertains to make and use the same.

This invention relates to new and useful in'iprovements in smoking pipes and more particularly to pipes constructed of molded material, to wit :such material as will withstand the heat as well as the moisture, and the primary object of the invention is to provide a device of this character which is so constructed as to enable the stem and bowl thereof to be readily cleaned.

A further object of the invention resides in providing a pipe, a portion of the bowl and the stem of which are slotted to receive a separable section which fits snugly in Place when applied.

A further object of the invention resides in providing a section or key portion which is designed to complete the formation of the bowl and which is designed also to complete the formation of the outer end of the integral stem of the pipe.

Still another objectof the invention resides in providing projections or portions on the key section or removable section of the pipe which have beveled portions thereon designed to aid in the positioning of said section in place when applying the parts one to the other. I

Still another object of the invention resides in providing a device which is simple, and durable in construction, inexpensive to manufacture and one which will be very efficient in carrying out the purpose for which the same is designed.

With these and other objects in view my invention consists of the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawing forming a part of this application: Figure 1 is a side elevation of a pipe constructed in accordance with my invention; Fig. 2 is a vertical longitudinal section therethrough; Fig. 3 is a vertical transverse section through the same as seen on line 33'of Fig. 2; Fig. 4c is an end elevation of the pipe with the removable stem and ferrule removed; and, Fig. 5 is a perspective view ofthe key or removable section of the pipe removed.

In describing. the invention I shall refer to the-drawing in which similar reference characters designate corresponding parts throughout the several views and in which 1 indicates a pipe comprising a bowl 2, an integral stem 3 and a removable stem 4, the latter having its inner end tapered and adapted to be wedged into place in the outer end of said integral stem 3. The integral stem 3 is provided with a longitudinal slot. or key wayfi which continues the full length of said stem forming a continuation of the bore 6 thereof. The inner end of this slot or key-way 5 terminates in the bowl 3 and continues a short distance upwardly in the bowl as indicated at, 7, thus forming an L- shaped slot or key-way in the complete pipe. The upper wall of this portion 7 of the slot or key-way is beveled downwardly as indicated' at 8 for a purpose to be hereinafter and more particularly set forth. 4

That portion of the slot or key-way formed in the stem 3 has the side walls thereof tapered inwardly from the upper to the lower edges thereof and fitting in the complete slot or key-way is a key or section 9 formed preferably of metal but which may be formed of any other desired material. The side walls of this key or section 9 are also beveled coincident to the beveling of the wallsof the key-way 5 so as to be wedged in place and the extreme inner end thereof is curved and grooved as indicated at 10 to complete the formation of the bowl 2 when Said key is positioned properly. The'inner end of said key 9 is also provided with an upwardly extending projection 11 which is designed to fit snugly in the portion 7 of the key-way and the upper wall of said projection 11 is beveled as indicated at 12 coincident to the beveled wall 8 of said key-Way portion 7. Thus when said key is applied in position the beveled walls contacting one with the other will tend to force said key downwardly into its proper position. The outer end portion of this key 9 is oifset as indicated at 13 to complete the formation of the outer end of the stem 3, the offset portion providing a shoulder whereby to receive thereagainst the inner end of the removable stem 4-. The upper edge of this key 9 is also provided at a point adjacent the offset portion 13 with a projection 14, the outer end wall of which is beveled as indicated at 15 for a purpose to be hereinafter and more particularly set forth.

t must be here stated that the outer end of the stem 3 is threaded as indicated at 16, such threads, however, extending only for the lower half of the periphery of said stem. Engaged with this threaded end of the stem 3 is an internally threaded ferrule 17 the inner peripheral edge of which is adapted to engage the beveled end 15 of the key section 9 to force the latter forwardly and downwardly in its place in the stem 3. It will be appreciated that all wear between the key section 9 and the stem 3 and the bowl 2 will be compensated for by the beveled portions hereinbefore mentioned and said key section may at all times be forced to fit snugly into place by the proper action of the ferrule 17 thereon.

As stated at the outset of the specification. the pipe is preferably formed of molded material and in view thereof it is advantageous to only provide the threads as described above to extend partially around the periphery of the stem 3. This is for the purpose of allowing the pipe to be drawn readily from the mold. The smooth portion of the periphery of the stem will afford a clearance for the threads of the ferrule which is applied to the threaded end of the stem, as clearly seen in Fig. 2 of the drawing.

From the foregoing it will be seen that I have provided a simple, inexpensive and efficient means for carrying out the objects of the invention and while I have particularly described the element best adapted to perform the functions set forth, it is obvious that various changes in the form, proportion and in the minor details of construction may be resorted to, within the scope of the appended claims, without departing from the spirit or sacrificing any of the principles of the invention.

Having thus described my invention, what I claim is:

l. A smoking pipe including a bowl, a

stem formed integral thereon having a smoke duct, the outer end of said stem being threaded, said stem being provided with a longitudinal key-way opening at its inner side in the said smoke duct and terminating in and continuing for a portion of thej length of said bowl, the upper wall of said key way in the bowl being beveled, a key section snugly fitting the key-way in said stem and having a projection at the inner end thereof fitting the key way in the bowl, the upper end of said projection being beveled coincident to. the beveling of the wall of said bowl, an upwardly projecting lug formed adjacent the outer end of said section, and means engaged with the outer threaded end of said stem and the projecting lug on the outer end of the section to force the latter in place.

A smoking pipe including a bowl, a stem formed integral thereon having a longitudinal smoke duct therein, said stem having its outer end threaded and being provided with a longitudinal key-way opening at its inner side in the said smoke duct and terminating in and continuing upwardly for a portion of the length of said bowl, the upper wall of said keyway in said bowl being beveled, a wedging key section fitting the key-way of said stem and having its inner end designed to conform to the inner outline of said bowl, a projection also formed on the inner end of said key-section fitting the key-way of said bowl and having its upper end beveled coincident to the beveled wall of said bowl, an additional projection formed on the upper edge of said kcy section adjacent its outer end and having the outer end wall thereof beveled and an internally threaded ferrule engaged with the threaded end of said stem and adapted for engagement with the beveled end wall of the last mentioned projection to force and lock said key section in place.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
